METHOD OF AND APPARATUS FOR TESTING LIQUIDS AND OTHER MATERIALS.

To all 'whom it may concern:

. Be it known that we, BELA SAGI afld EUGEN SAGI, both subjects of theKing of Hungary, residing at Budapest, Austria- Hungary, have jointlyinvented certain new and useful Improvements in Methods of and Apparatusfor Testing Liquids and other Materials, of which the following is aspecification.

The object of this invention is to provide means whereby a personunskilled in making tests may readily procure the testing of a sample ofsome liquid, either to ascertain whether or not the same is pure, if afood product for instance, or in case of urine to ascertain the presenceof sugar or albumen,-

or diseased material.' It not only affords the unskilled with the meansof effecting such tests, but also provides those who have frequently tomake the same tests upon samples of like material, a ready means ofaccomplishing the same without recourse to the tedium of detail in eachinstance.

In the accompanying drawings there is illustrated a practical embodimentof mechanism for carrying out our improved method. This apparatus isparticularly intended for the testing of urine.

In these drawings,Figure 1 is a front elevation of the apparatus; Fig. 2is a central vertical section taken on about the plane of the line 22 inFigs. 1 and 6; Figs. 3, 4 and 5 show positions assumed by the measuringreceptacle or gage which is employed for receiving a predeterminedquantity of the liquid to be subjected to the test; Fig. 6 is a verticalsection of the device taken on about the plane indicated by the line 66in Fig. 2; Fig. 7 isa horizontal section of the upper portion of theapparatus taken on about the plane of the line 77 in Fig. 2; and Fig. 8is a horizontal section of the lower portion of the apparatus.

This improvement is useful for'testing samples of various liquids. The.operator has simply to supply a quantity of liquid, preferably in excessof that required for the test, deposit this in the machine, which willtake the required sample or a plurality of these from the liquidsupplied, and upon manipulation of an actuator the test will proceed andthe results be displayed to the operator. A urine testing machine ishere-' in described and shown as illustrative of the invention.

In the front elevation of the device there are shown two test tubes A Adisplayed through a window A and under these the basin of theurinal B,.After urinating into the basin or introducing into the same a quantityof urine, the driving mechanism parts, but also of adding to the rinsingwater certain material necessary for dissolving the precipitate.

The materials used for testing and the reagents are shown stored inbottles F F F F which are connected by means of suitable tubes 7, f f f,at their upper portions and tubes f' f f f at their lower portionsrespectively with thevessels E E E E Below these vessels there aredisposed two funnels D D with which the vessels above referred toare incommunication. Each ofthe vessels above referred to is provided with astopper, which stoppers are indicated by 6 e 6 e,.- The liquid in thevessels above referred to is preserved at the proper level in accordancewith Mariottes principle.

The stoppers above referred to are actuated by theoperating mechanism tobe described later, in such a manner that the desired quantity of liquidwill becaused to pass to the funnelsD D, at each testing operation. Thefunnels D D are disposed above and empty into the test tubes A Arespectively. v

The heating necessary for detecting the sugar reaction is brought aboutby means of the gas burner G arranged on the side of the test tube A Theburner is controlled by means of a gas cook Gr in the gas conductor g. Apilot flame Gr is employed for effecting the lighting when the gas cockis open. The means for regulating the intensity of the flame are notillustrated.

- The mechanism will be driven by some suitable force. In the presentillustration a gravity motor is illustrated which is operated in thepresent instance by means of the water used for flushing certainportions of the apparatus. The urinal basin B, d1scharges part of theliquid deposited 1n it into the gages or samplers, and the excess flowsinto a sink or hopper P There is located above this sink a tank S whichis supplied with water from a suitable pipe 5, controlled by a ballvalve S A tank R is mounted in a vertical guideway and is provided witha rope 0 passing over a drum 0, and having a weight 1' There are a pairof these drums and ropes, one for each end of the tank R, loose upon thedriving shaft 0. When the tank Ris empty, it will be raised by thecounterweights into position to engage the tripping device 43,, and bymeans of the connections 8 will open the discharge device 8 of the watertank S and permit the predetermined charge of water therein to flow intothe tank R. The tank R is held in its elevated position by means of thedetent k,. The tank R is provided at its bottom with a valve 1', havinga de-' pendent stem r which will be tripped when the tank R reaches itsdown position by means of a tripping device comprising an upstanding pin72,. The drums 0, are loose upon the shaft 0, and each has fast .with ita ratchet wheel 0 which transmits motion to the driving train by meansof a pawl 0,. The driving train comprises a pair of gear wheels 1 on theshaft 0 meshing with wheels 2 on the shaft M, which shaft carries awheel 3 meshing with awheel 4 on the cam shaft L.

The speed communicated from the gravity motor will be controlled in somesuitable manner. There is illustrated a brake disk adapted to bedrawnagainst a friction surface Q, to regulate the speed.

The opening and closing of the various stoppers and cocks at thepredetermined times are effected by means of properly timed cams La, LaLe, Le Le Le, Lg L11 keyed upon the cam shaft L, which from the fact ofits controlling the various operations can properly be called thecontrol shaft. The cams above referred to operate the parts by'means oflevers ha, ha, he, he, he he, by Iw. The lever arms may be provided withantifriction rollers for engaging the cams.

The receiving basin B, has located beneath it a funnel B provided withtwo outlet branches b In the upper portion of the funnelwill be locatedsome suitable filtering material 6,. Each of the funnel branches willlead to a sample measure or gage C, C The illustrative embodiment of theinvention provides for simultaneously gages are illustrated in detail inFigs. 3, 4 and 5. The Fig. 5 position shows the gage slightlytipped, sothat when the liquid is presented to it b, means of the funnel and ithas received al it is capable of receiving while in its tipped position,it will be only partially full when it is caused to assume its uprightposition, the position illustrated in Fig. 4. By this means apredetermined quantity of liquid may be placed in the gage and withsafety transported to the point of delivery.

The sample measures or gages are shown mounted upon a shaft 0, journaledin the frame 0 This frame is mounted in a vertical guideway and issufficiently heavy to assume its lower position by gravity. A tippingarm a, is journaled in the frame upon a pivot 0,, for each of the gages.The forked end of this arm engages a pivot 0 on the gage. A spring 0,,holds the gage in Y the upright position, the position illustrated inFig. 4, wherein the bottom of the gage is en aged by a limiting orpositioning lug 0-,. Then the gages are in their lower position, namely,the dotted .line position in Fig. 2, and the position shdwn in Fig. 5, aportion 0,, of the arm 0 will engage the surface 0,, and slightly tipthe gage. When the gage arrives at the top of its guideway, a portion0,, of the arm W111 engage an abutment 0, and empty the contents of thegage. The contents of gage C, will empty into funnel D,, and thecontents of gage C. will empty into funnel D The elevation of thesamples is produced in the illustration in the following manner: Apair'of drums M, are mounted free upon the shaft M, and to these drumsthere are fastened the cables 0,, connected to the frame 0 which carriesthe gages. A pawl m, is fast upon the shaft M. A pawl lever m is pivotedby means of a pin m, to one of the drums M,, which are fastenedtogether. A spring m, controls the action of the pawl lever m Theoperation of the machine is substantially as follows: The liquid to betested will be placed in the basin 3,, as for instance by theoperatorurinating therein. The liquid will be filtered and pass outthrough the funnel branches 6,, and a sample of predetermined volumeplaced in the measuring gages C, 0 The excess of the supply of liquidwill enter the hopper or sink P and pass from there by means of the trapThe operator will then take hold of the handle K, and draw this out, thedrawing out of which handle will withdraw the detent 70, from below thewater tank R and permit this tank to descend, the descent of which watertank will supply the driving force to'the various portions of themechanism. The frame will be acted upon and elevate the gages. As soonas the tilting arms "a, ;are moved out of en- 1,1es,eea

gagement with the surface 0,, the gages will be turned into theirupright positions, in which positions there is a margin of safetyagainst the contents slopping out. The pawl hm, actuated by the cam diskLm of the controlling shaft, releases the pawl m and permits the drums Mto rotate and bring the gages to their upper position, wherein theportion 0 of the tilting levers will engage the abutment c and tip thegages into the positions illustrated in Figs. 2 and 3, whereby the twosamples of liquid will be deposited in the respective tubes. Therotation of the control or cam shaft L will then actuate the variouslevers and bring the desired testing materials into the proper testtubes and apply the heat to the test tube which is to be heated. Theoperator standing in front of the apparatus will watch the reactionstaking place in the test tubes through the window A If the apparatus isintended for use of the general public or those not skilled in the artof making the tests, certain printed instructions will be displayed insome conspicuous place, so that the operator may know from the reactionstaking place within the test tubes, the result of the test which isbeing made. The mechanism will be so timed that after a suflicientinterval for observation has elapsed, the stoppers a a, in the lowerends of the test tubes will be unseated, and the contents permitted topass through the discharge pipe 1? which leads to the sink P At the sametime the lever he will be actuated by means of the cam Lv' which willopen the cock V in the water supply pipe '0 A branch pipe v, has nozzlesfor discharging into the gages while still held in their tilted positionof Fig. 2, the rinsing water running from these gages into the funnels,and from thence into the test tubes. A branch pipe '0 is provided forrinsing the test tubes, it havin nozzles '0, 1), arranged tangentiallyto t e wallsof the respective test tubes, in order that the rinsingwater may run in a spiral along such walls. A pipe 1),, is provided forrinsing the basin B During the'first part of the rinsing, it is founddesirable to dissolve the precipitate by use of a few drops ofhydrochloric acid, which will be caused to pass from the suitablebottle, as forinstance the bottle F The mechanism is so timed that afterthe rinsing is accomplished, the valve V will be closed, and the frame 0carrying the sample gages will be returned to their initial positionready to receive a fresh sample. Ihe water tank R will then reach itslowest position wherein the valve 0", will be unseated to permit thecontents of the tank R to discharge through the sink P and rinse out allthe liquids which have been deposited therein. Ihe tank R being nowempty will be free to respond to its counterweights 1' and be elevatedinto its position to again receive a charge of water from the tank S.
